Hola is the first community powered (Peer-to-Peer) VPN, where users help other users make the web world-wide again. This means that Hola routes your traffic through other peers (nodes) in the Hola network, as opposed to routing through power-hungry costly servers. This allows Hola to provide you with a superior VPN service with minimal underlying costs. HolaCDN’s use of uses real peers to route your traffic, rather than proxy servers, makes you more anonymous and more secure than regular VPN services. This also means that Hola is harder to detect and block. Currently, Hola runs in a hybrid mode – combining traditional VPN architecture and peer-to-peer technology. Chrome browser extension and Opera browser add-on operate as a standard VPN service, and are not part of the Hola peer-to-peer network.
Hola is not a standard VPN service but a peer-to-peer VPN, where users connect not to a VPN server but to another user's router. It raises major privacy concerns because when you use it, you cannot control who uses your Internet bandwidth. However, Hola VPN has more than 100 million users because it is free and simple to use on a mobile device.
